Improvement in harvesters



JACOBS w. SCIIUCKEES, oE PHILADELPHIA, PENNSYLVANIA, AssIGNoE To UNITED STATES PATENT OFFICE- ISAAC A. SHEPPAED, oE SAME'PLACE.

IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 111,482, dated January 31, 1871.

To all 'whom t may concern Be it known that I, JACOBS W. SCHUCKERS', of the city and county of Philadelphia, State of Pennsylvania, have invented a Certain new and useful Improvement in Harvesters, of which the following is a specification, reference being had to the accompanying drawing, in which- Figure 1' represents a plan view of so much of a machine as is necessary to illustrate my invention; 2, a vertical longitudinal central Section through the same in the line of the main axle 5 Fig. 3, a view, in perspective, of the gearing, with a portion of the nearest wheel broken away to show the parts behind it; Fig. 4, an elevation of the stubble side of the same with the inner driving-wheel removed.

The invention herein claimed relates only to the gearing. The other features shown form the subject-matter of another application.

The machine herein delineated is so well known in most of its details as to require merely a reference to its constituent parts.

Two driving-Wheels, AA', revolve freely on an axle, B, with which they are connected by backing ratchets or clutches a.. The axle B revolves freely in pipe-boxes b on the main frame C, Which is of metal, and cast in such shape as to inclose the gearing. A tongue, D, projects from the inner front corner of this frame. A finger-beam, E, is secured to a shoe, E', having lugs upon it, by means of which it is pivoted to the lower end of a coupling-arm, F, the outer end of which is swiveled to the under side of the frameat f. A brace-bar, Gr, is pivoted at one end to the frame, and at the other to the coupling-arm. A lifting-lever, H, is pivoted to the frame. An arm, h, of this lever, extending upward from its pivot, is pinjointed to a link, e', in turn similarly pivoted to a rocking sector, I, having a groove in its face for the reception of a chain, i', which is also attached to the nger-beam at a point outside of the shoe, by which means the finger-beam is not only lifted from the groimd at both ends, but its divider end is also lifted higher than its heel end.

An internallygeared spur-wheel, J mounted upon and turning with the main axle, drives a spur-pinion, j, mounted on a stud-axle on an arm, c, of the frame. This pinion drives acorresponding one, k, on a sleeve, k1, which revolves freely upon, and `independently of, the main axle, and carries a second internallygeared spur-Wheel, lf, which in turn drives a spur-pinion, k2, mounted in bearings on the frame, like its fellow j.

The pinion k2 drives a small spur-pinion, Z, which runs in a recess in the Spur-wheel k, and is mounted on a sliding sleeve, l', which is movable freely on the axle B by means of a shipping-lever, L. A clutch on this sleeve engages with a bevel-wheel, M, revolving freely on the main axle, and driving a corresponding' pinion, n, on a crank-shaft, N, which drives the cutters by a crank 'and pitman.

The object of this method of arranging the gearing is to secure compactness and a high speed of the cutters, which is essential in mow.

In this instance the relative proportion of the gearing is such as to produce about forty revolutions of the crankshaft to one ofthe main drivin g-WheelsA A' This relative speed might, obviously, be varied by changing the relative numbers of the teeth of some of the gears, as is Well understood by mechanics.

I am aware that multiplyinggear heretofore has been mounted on the main axle of a harvester, and therefore do not, broadly, claim every mode of doing this.

I claim as my invention- The combination .of the internally-geared spur-wheel J, revolving' with the main axle, the pinion j, mounted on the frame, the pinion 7c on the collar k1, the internally-geared spurwheel, revolving' loosely on the main axle in a direction opposite to that of its fellow j, the pinion k2 on the frame, the pinion l on the sliding sleeve, the clutch, the bevel-wheel loose on the main axle, and the crank-shaft, all these parts being constructed and operating as described.

In testimony whereof I have hereunto subscribed my name.

JACOBS SCHUCKERS.
